This paper introduces the monitoring requirements, diagnostic principles and calibration objectives of the CN6 On-Board Diagnostic (OBD) on cooling system. For the traditional calibration method which has a huge workload and a long calibration period, Simulink was used to build the monitoring model of the cooling system in the controller, and the off-line calibration method was used to calibrate the cooling system of a 1.2 L direct-injection supercharged gasoline vehicle. The off-line calibration results meet the development objectives, and the calibration cost and calibration cycle are reduced by more than 2/3.
